Okay, so it turns out that this is an in-game event that’ll go on for three weeks, in which you can unlock a different Angry Birds Epic character each week by collecting tokens. That, or you can just buy them. These includes Red ‘Knight’, Chuck ‘Mage’ and Bomb ‘Pirate’. You’ll still be able to use keep using these characters even after unlocking them. This event will be on all three platforms: iOS, Android and Windows Phone.

So uh, yeah, medieval Angry Birds characters in a Sonic game. Just in case for if you weren’t weirded out already by the Sonic Twitter suddenly becoming a lot more meta.
